摘　　要：目的 观察在当今时代下云南省不同年龄男性汉族耻骨联合面形态的变化情况,探讨耻骨联合面形态变化与死者年龄的线性关系,以建立一个适用于云南男性汉族人口的耻骨联合面形态变化推断年龄的方程式,并与现行通用方法进行比较.方法 利用日常尸检工作中收集到的85付年龄在17 ～ 50岁之间的有死亡时年龄的确切记录的云南汉族男性耻骨联合面为标本（病变及破损的标本一律剔除不用）,选择6个观测项目进行形态变化的观察并制定相应的评分标准,依据该标准对耻骨联合面形态变化进行评分,然后采用多元线性回归方法对所得数据进行处理,建立了云南男性汉族人口耻骨联合面形态变化推断年龄的方程式.结果 根据上述方法建立了云南男性汉族耻骨联合面形态变化推断年龄方程：y=15.884＋ 1.466 X1＋1.777 X2 ＋2.040 X4＋1.504X5 ＋3.006X6.结论 所建立的云南男性汉族人口的耻骨联合面形态变化推断年龄的方程式在推断云南汉族男性尸体年龄推断时结果更准确.Objective To observe the changes of Han male pubic symphysis surface morphology with different age in Yunnan province, analyze the correlation between pubic symphysis surface morphology and age, and establish an equation for inferring age. Methods We collected 85 Yunnan Han male pubic specimens in daily work, their ages between 17-50 years , and had exact records about ages （specimens of all lesions and removed without damage） . We selected six morphological changes in the project to observe and develop appropriate assessment criteria, based on the standard morphological changes on the surface of the pubic symphysis to score, and then usd multiple linear regression method for processing the data obtained, finally, established an equation for inferring age according to Yunnan male pubic symphysis surface morphology. Results With the above method, we established the equation for inferring age according to Yunnan male pubic symphysis surface morphology： Y = 15.884 ＋ 1.466 X1＋ 1.777 X2-4-2.040 X4d-1.504 X5＋3.006 X6. Conclusion The equation we established is more better than before in practical applications.
